Is proximity to a food retail store associated with diet and BMI in Glasgow, Scotland?

Background: Access to healthy food is often seen as a potentially important contributor to diet. Policy documents in many countries suggest that variations in access contribute to inequalities in diet and in health. Some studies, mostly in the USA, have found that proximity to food stores is associated with dietary patterns, body weight and socio-economic differences in diet and obesity, whilst others have found no such relationships. We aim to investigate whether proximity to food retail stores is associated with dietary patterns or Body Mass Index in Glasgow, a large city in the UK.
Methods: We mapped data from a ‘Health and Well-Being Survey’ (n = 991), and a list of food stores (n = 741) in Glasgow City, using ArcGIS, and undertook network analysis to find the distance from respondents’ home addresses to the nearest fruit and vegetable store, small general store, and supermarket.
Results: We found few statistically significant associations between proximity to food retail outlets and diet or obesity, for unadjusted or adjusted models, or when stratifying by gender, car ownership or employment.
Conclusions: The findings suggest that in urban settings in the UK the distribution of retail food stores may not be a major influence on diet and weight, possibly because most urban residents have reasonable access to food stores

Investigation of population heterogeneity of diet use among middle-aged Australians

The purpose of the study was to determine patterns of diet use among middle-aged Australian men and women and the relationships between these different usage patterns and demographic characteristics, health status and health habits. A cross-sectional mail survey was conducted among a random sample of 2975 people aged 40–71 years in Victoria, Australia. A total of 1031 usable questionnaires were obtained which included information about the use of diets (e.g. low-fat and low-salt) during the past 3 months along with demographic information, health status and health habits. Based on the responses about the use of thirteen diets for both sexes, latent class analysis was employed to identify the optimal number of use of diets and the assignment of participants to particular groups. Three types of diet uses were identified and provisionally named: diet use, selected diet use and non-diet use. This classification was associated with demographics, health status and health habits, and these associations differed between men and women. The findings suggest that nutrition education programmes should be tailored to the different needs of the diet use groups.

The association between habitual diet quality and the common mental disorders in community-dwelling adults : The Hordaland health study

Objective Recent evidence suggests a role for diet quality in the common mental disorders depression and anxiety. We aimed to investigate the association between diet quality, dietary patterns, and the common mental disorders in Norwegian adults.

Methods This cross-sectional study included 5731 population-based men and women aged 46 to 49 and 70 to 74 years. Habitual diet was assessed using a validated food frequency questionnaire, and mental health was measured using the Hospital Anxiety and Depression Scale.

Results After adjustments for variables including age, education, income, physical activity, smoking, and alcohol consumption, an a priori healthy diet quality score was inversely related to depression (odds ratio [OR] = 0.71, 95% confidence interval [CI] = 0.59–0.84) and anxiety (OR = 0.77, 95% CI = 0.68–0.87) in women and to depression (OR = 0.83, 95% CI = 0.70–0.99) in men. Women scoring higher on a healthy dietary pattern were less likely to be depressed (OR = 0.68, 95% CI = 0.57–0.82) or anxious (OR = 0.87, 95% CI = 0.77–0.98), whereas men were more likely to be anxious (OR = 1.19, 95% CI = 1.03–1.38). A traditional Norwegian dietary pattern was also associated with reduced depression in women (OR = 0.77, 95% CI = 0.64–0.92) and anxiety in men (OR = 0.77, 95% CI = 0.61–0.96). A western-type diet was associated with increased anxiety in men (OR = 1.27, 95% CI = 1.14–1.42) and women (OR = 1.29, 95% CI = 1.17–1.43) before final adjustment for energy intake.

Conclusions In this study, those with better quality diets were less likely to be depressed, whereas a higher intake of processed and unhealthy foods was associated with increased anxiety.

Maternal health in Lao PDR : repositioning the goal posts

This paper reviews attempts made in the Lao People's Democratic Republic (PDR) to achieve Millennium Development Goal (MDG) 5: Improve Maternal Health and its two targets: (1) to reduce by three quarters the maternal mortality ratio and (2) to achieve universal access to reproductive health. It will be shown that significant strides have been made in relation to both the targets, especially in the province of Xayaboury where the contraceptive prevalence rate is the highest and maternal mortality is the lowest in the country. That said, it is unlikely that either target will be realised by 2015 for the nation as a whole. Some of the reasons for this are canvassed such as problems with the existing health infrastructure and its personnel, the cost of health care, the demographic profile and cultural expectations of women of childbearing age, geographic barriers, the absence of communication and transport infrastructure and the influence of international donors on how monies are expended. As discussions now begin to set the framework for the post-MDG compact of the international community to address poverty and well-being, it would be valuable to consider the multiplicity of factors which directly impact maternal and infant mortality rates (such as family planning, age at first birth, access to antenatal care and government expenditure on maternal health care) and explain what causes change, over non-contextualised statistics that simply report changes.

Reversed sexual dimorphism and altered prey base : the effect on sooty owl (Tyto tenebricosa tenebricosa) diet

The ecology and function of many Australian predators has likely been disrupted following major changes in prey base due to declines in distribution and abundance of small mammals following European settlement. This study investigated various aspects of the dietary ecology of sooty owls (Tyto tenebricosa tenebricosa), including sexual variation as they potentially exhibit the greatest degree of reversed sexual dimorphism of any owl species worldwide. Sooty owls are highly opportunistic predators of non-volant small mammals, consuming most species known to exist in the region, so their diet fluctuates seasonally and spatially due to varying prey availability, and is particularly influenced by the breeding cycles of prey. Significant intersexual dietary differences existed with female sooty owls predominantly consuming much larger prey items than males, with dietary overlap at 0.62. The current reliance on relatively few native mammalian species is of conservation concern, especially when mammal declines are unlikely to have ceased as many threatening processes still persist in the landscape. Sooty owl conservation appears inextricably linked with small mammal conservation. Conservation efforts should be focussed towards improving prey densities and prey habitat, primarily by implementing control programs for feral predators and preventing the loss of hollow-bearing trees throughout the landscape

Maternal predictors of preschool child-eating behaviours, food intake and body mass index : a prospective study

This study extends McPhie et al. (2011)'s [Maternal correlates of preschool child eating behaviours and body mass index: A cross-sectional study. International Journal of Pediatric Obesity, Early Online, 1–5.] McPhie et al. (2011)’s cross-sectional research, by prospectively evaluating maternal child-feeding practices, parenting style and mother–child interactions as predictors of child-eating behaviours, food habits and weight. A sample of 117 mothers of preschoolers (63 girls, 54 boys) participated at two time-points, Time 1 (T1) and Time 2 (T2), 12 months apart. Results from the two path models revealed maternal pressure to eat at T1 positively predicted change in child enjoyment of food. Maternal warmth at T1 negatively predicted child unhealthy food habits at T2. At T1, family income and maternal control negatively predicted change in child body mass index z-scores (BMIz); maternal pressure to eat at T1 also positively predicted change in child BMIz. There were significant results specific to each model. Both final path models provided an adequate fit. Our findings suggest childhood obesity is predicted by a complex interplay of demographic, maternal and child variables.

Associations between mothers’ perceptions of the cost of fruit and vegetables and children’s diets : Will children pay the price?

Background/Objectives:
Perceptions that fruit and vegetables are expensive are more common among the socio-economically disadvantaged groups and are linked to poor dietary outcomes. Such perceptions may be exacerbated in countries recently affected by natural disasters, where devastation of fruit and vegetable crops has resulted in increase in prices of fruit and vegetables. Examining the associations of perceptions of fruit and vegetable affordability and children's diets can offer insights into how the high prices of fruit and vegetables might have an impact on the diets of children.
Subjects/Methods:
We analysed the data from 546 socio-economically disadvantaged mother–child pairs to assess the relationship between maternal perceptions of fruit and vegetable affordability and the diets of their children.
Results:
Fruit consumption was lower among children whose mothers felt the cost of fruit was too high. Maternal perceptions of fruit and vegetable affordability were not associated with any other aspect of child's diet.
Conclusions:
Our results suggest a possible role for maternal perceptions of fruit affordability in children's diet, though further research is warranted.

Associations between dietary patterns at 6 and 15 months of age and sociodemographic factors

BACKGROUND/OBJECTIVES: Data from the Avon Longitudinal Study of Parents and Children (ALSPAC) have previously shown that dietary patterns are observable by 3 years. However, it is not clear when dietary patterns emerge. We aimed to describe dietary patterns in early life and their associations with maternal and infant sociodemographic characteristics.

SUBJECTS/METHODS: Principal component analysis was applied to diet questionnaires of ALSPAC participants at 6 months (n=7052) and 15 months (n=5610) to extract dietary patterns. The sociodemographic factors associated with dietary patterns were investigated using regression analyses.

RESULTS: Four dietary patterns were extracted at both 6 and 15 months. A traditional-style pattern characterized by home-prepared meats, vegetables and desserts, a second pattern characterized by ready-prepared baby foods and a third pattern characterized by discretionary foods such as biscuits, sweets and crisps were identified at both ages. At 6 months, the fourth pattern was characterized predominantly by breastfeeding and at 15 months, by contemporary-style foods including herbs, legumes, nuts, raw fruit and vegetables. Higher maternal age and education, number of siblings and lower body mass index (BMI) was associated with higher scores on the breastfeeding or meat, vegetables and desserts patterns, whereas higher discretionary food pattern scores were associated with younger maternal age, lower education, higher BMI and more siblings. Associations between sociodemographic factors and the ready-prepared baby food pattern scores were inconsistent across ages.

CONCLUSIONS: Dietary patterns emerge from infancy and are associated with sociodemographic characteristics.
